Hello, i am ahving problems with a new install on another machine, when i try and run emerge sync or try and emerge an app it fails with name resolution error.
I have checked configs against my main machine which is working fine and all seems ok.
error for emerge sync
| Code: |
root # emerge sync
Notice: (-2, 'Name or service not known')
>>> starting rsync with rsync://rsync.europe.gentoo.org/gentoo-portage...

As said i have main computer on same network with same settings and it works fine.
Think it maybe due to the fact that this install was done on main machine in chroot the tarballed and copied over to new machine. A coupe of apps i have installed do not work so think that the tar did not get all files.
What app would i need to rebuild to cure this issue?
can copy ebuild from main pc ok.

pet peeve of mine that gentoo doesn't arrive with bind-tools or vim....
try ping 4.2.2.1 (genuity name server).
set resolv.conf with nameserver 4.2.2.1.
try again.

also try in /etc/hosts...
130.230.54.100 rsync.europe.gentoo.org
Also, make sure you have tcp allowed inbound of port 53 to your host. SOmetimes large dns replies are sent using tcp rather than UDP, and confuses some firewalls. rsync.europe.gentoo.org pulls down a pile of A records.

thanks for replies, true nameserver suggestion but did not work, like i said i can connect from main pc ok, can connect form the chroot install on main machine but when i move new install over to new box this is when i get the problems.
Now i do have hardened in USE= but only using gento-dev-sources at moment, will move over to hardened kernel once get system working.
What could be stopping system reaching firewall/router but allowing connection to other boxs on network?

Can you ping your firewall from other machines?
You never mentioned if you tried to ping that ip address (4.2.2.1). If you can't reach the Internet, you have to figure out why that is.
Do you have an IP address conflict with that other server you mentioned? Maybe the firewall has that server's mac in its arp table for your new machine's IP address. Try to ping your new box from the firewall and verify macs with an "arp -a" on the firewall. Flush the firewall's arp cache, reboot the firewall, ... stuff along these lines seems like logical troubleshooting given your ping problem.

I am having the same problem. I have also installed gentoo-dev-sources.
Kerenel 2.6.9-r9.
I have managed to download about 1 in 15 tries. The error I seem to get is in the euro site ftp://ftp6.uni-erlangen.de
I have tried to bypass the firewall and it didn't make any difference. Still get the Temporary Name Failure in ....

yaps i'am having the same trouble and the mirror uni erlangen.de is my favourite download location... what we gonna do? and what is it exactly? i tried many kernel options and in my local network everything goes fine (more or less).
sometime my pc freezes by trying to abort emerge --sync... and i need to do it.
so i got no data through the interne to fix this... does this mean... i got to reinstall gentoo. (stage1 installation which took me muchas horars)
...
(i got a nforce 3 150 ((could be interisting)))
(and i got the same kernel as my pal's above me) |

Hello, this not a network problem as other gentoo boxs connect fine with same settings, it is something with this new install and has happened on last two installs.
What settings could it possible be?

Have you checked your /etc/resolv.conf for correct dns servers
and what do you get when you type
whats the default IP
For eg.
| Code: | lithium ~ # ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:0D:88:36:C9:24
inet addr:192.168.70.55 Bcast:192.168.70.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:238177 errors:0 dropped:0 overruns:0 frame:0
TX packets:16095 errors:0 dropped:0 overruns:0 carrier:0
collisions:7 txqueuelen:1000
RX bytes:37460375 (35.7 Mb) TX bytes:1620487 (1.5 Mb)
Interrupt:18 Base address:0xec00
lithium ~ # route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
192.168.70.0 * 255.255.255.0 U 0 0 0 eth0
loopback lithium.local 255.0.0.0 UG 0 0 0 lo
default 192.168.70.1 0.0.0.0 UG 0 0 0 eth0
lithium ~ # |
Thats my net settings.
from ifconfig I can verify that i have correct ip, broadcast and sunet
from route I can verify that my gateway is set correctly
and moreover my resolv.conf has correct dns servers
Have you checked all of that...while also ensuring that you don't have a duplicate ip on the network.

It appears that the nameservers for uni-erlangen.de are messed up. But that isn't the original poster's problem. His problem was that a specific box on his own network couldn't sync across the Internet whereas another one could. So these additional postings about uni-erlangen.de don't apply to him.
For the uni-erlangen.de problem, the uni-erlangen.de nameservers need to be corrected. Since the SOA record shows the responsible mail address within the uni-erlangen.de domain itself (and hence doesn't resolve), that's no help. I haven't been a dns administrator for about 10 years now and don't know how to figure who to contact for uni-erlangen.de. I can't find any info with an INTERNIC whois.

You haven't answered any of the questions posed to you to elaborate on what exactly your problem is. The problem is that this new box you've setup can't get packets past your firewall to the Internet, right?
Can you ping 4.2.2.1?
Can you resolve *any* names?

I have checked resolv.conf and that is ok, except for ip address it is same as working system. IP does not conflict with on network.

Yes i can ping 4.2.2.1, i can also ping the box from firewall, and from the box i can other pc on network.
What i can't do is connect to the net from box concerned, nether can i ssh to it or from it, i do have hardened in USE= so wondering if some security setting may need editing?
cheers

Ok sorted, in resolv.conf i had
| Code: |
domain mydomain.com
nameserver 192.168.1.1
|
By having 'domain' instead of computer host name it was looking up the domains real nameserver rather then staying on local network.
Little bit further up that learning curve now 
thanks for help
